The Receivables Modules allows you to forecast your expected revenue and provides detailed tracking of billing information, invoices, payments, statements and invoice credits. With this module you can view individual invoices, apply payments to invoices, and even setup recurring billing. An accurate and current history of all charges, payments, services (requested or performed), and materials used is available. Additionally you can view a list of open invoices for each individual customer; and conversely apply payments from a customer across multiple invoices.
